  • Patent number: 10010640
    Abstract: An electronic scented candle is described that includes a flame piece, a shell including an installation chamber, a fragrance container that is removably positioned inside the installation chamber, a scent chamber, and a liquid suction channel positioned within the fragrance container. One end of the liquid suction channel protrudes from the fragrance container into the scent chamber and anther end of the liquid suction channel is positioned within the fragrance container to draw a fragrance material from the fragrance container to the scent chamber. A scent outlet in communication with the scent chamber allows scent from the chamber to reach an external environment of the electronic scented candle, and an air inlet in communication with the scent chamber directs air from the external environment to the scent chamber. A heating device heats the content of the scent chamber to allow rapid dissemination of the scent chamber into an external environment.

  • Publication number: 20180180236
    Abstract: An electronic lighting device and a method for manufacturing the same are disclosed. The electronic lighting device may comprise a core, which may comprises an enclosure, a light-emitting element, a flame sheet and a swing mechanism. The flame sheet is movably supported or suspended on the enclosure, and may comprise an upper sheet which is of a flame-like shape. The upper sheet is configured to expose above the top of the enclosure. The light-emitting element may be installed on the enclosure. A light outgoing direction of the light-emitting element may be intersected with the surface of the upper sheet so that the light of the light-emitting element is projected on the surface of the upper sheet. The swing mechanism is disposed beneath the flame sheet and can apply a force on the flame sheet to actuate the flame sheet to sway or swing. By the present application, a visual experience of true fire can be achieved and an interestedness and appreciation can be improved.
